## Overview

The Level Sense LS2600 Floor Water Sensor features a 30-foot cable and stainless steel sensing feet designed to detect liquid presence by closing a circuit when water contacts the sensor. Compatible with most home security systems and DIY electronics like Arduino and Raspberry Pi, it offers reliable flood and leak detection for residential and commercial spaces. With a durable ABS housing, 24V max voltage support, and included mounting hardware, it ensures easy installation and dependable performance in utility rooms, basements, and more.

## Description

Level Sense LS2600 Surface Liquid Sensor connects to an control device accepting a switch type contact. When water or other liquid makes contact on the metal sensing tabs, the sensor will short across the liquid providing a closed signal across the wires. When no water is being detected the wires will provide and open signal. The sensor is great for protecting computer and telephone room sub-floors, water storage tanks, water heater piping, bathrooms, laundry rooms, air conditioners, and refrigerator drip pans. Use only with non flammable liquids. Not for confined spaces. *Size: L64*W15.6*H12.7mm *Housing: ABS, white *Working Voltage: 5Vdc-12Vdc *Max. Voltage: 24Vdc *Max. Working Current: 0.5A *Temperature: -10℃ ~ +65℃ *Cored cable 6 feet *red wire to Positive, *white wire to Negative (ground) *Output: NPN type Perfect for Arduio, Rasberry Pi, and home electronics projects. Application Notes (based on Feedback of users with problems): There are no electronics inside this device. It does not provide a "contact closure". It is two stainless steel coated feet, connected to conductors in a plasticized sealed coating to provide corrosion a protected environment where the wires connect to the stainless steel feet. When the unit detects water, it operates as a resistor between 0.6M ohms and 1.4M ohms (i.e. the resistance of the water its detecting). In some applications it can be directly applied but generally speaking needs to be connected to a circuit that will sense the difference between 0V and the output voltage.

Review: Great product - Worked well.
Review: A good low DC voltage water sensor with a housing that is not water tight - The unit is a decent water sensor for what it does, but note that there is one flaw in the design. The ABS housing is not water tight, so if/when it is fully immersed, water tends to stay in the case and continues to conduct for a variable period of time after the water level recedes. It did not matter for my application, but it may for others. I've seen similar sensor units from other manufacturers that use epoxy resin to fully protect the internals from water, but they also cost more. Also note this is not simply two contact plates in a housing with connected wire. There is a BJT transistor and a couple resistors contained in the housing, thus the minimum requirement of 5V DC supply to drive it. The transistor acts as the control element for current. At lower voltages, the sensitivity is going to be negatively impacted and may not trigger reliably if you have very clean water. Two #4 x 3/4" Phillips flat head mounting screws are provided and an instruction sheet is included in the bag that lists the specifications as well as a few sample circuit diagrams for different applications.

## Questions & Answers

**Q: can this be used to turn off a 110V fan motor in a fan coil unit if leaking**
A: It can be used to detect the water, but would require it to be connected to a relay for it to directly switch a fan. If you look in the documentation there is a very simple circuit you can make with a solid state relay (search amazon for B00DDDFUZG). We recommend this relay because it is HORSEPOWER rated. This means that it has been tested for and is approved for use controlling motors. If you have DC power, this sensor, and the relay above, you can switch any motor load up to 3 HP, or any solenoid up to 50 amps.

**Q: Does it trigger when wet or submerged? if i use it for a wster pump, with a relay, would it stop as soon as the water level lowers or until dry?**
A: This device is not providing a “contact closure” it is providing a trickle current between the two contacts when water with some ionic content is present.
The Leak sensor behaves as an open circuit when no water is present, and behaves as a (roughly) 1.4MΩ resistor when water is present.
Water has to come in contact with both of the metal feet on the sensor to trigger a device. 
The leak sensor will continue to provide the trickle current until both feet are no longer in contact with water.

**Q: What is the upper temperature that this can handle?  can it be used to detect hot water from a water heater prv?**
A: Hello, 

The leak sensor is rated to handle temperatures up to 150F. 

I would imagine that this depends on how hot the water is that is coming from the hot water heater.

**Q: this sensor detect low resistance water ?**
A: Level Sense LS2600 Surface Liquid Sensor connects to a control device accepting an analog or digital input. 
If you are using this in home electronics projects, please take note of the following:
•	This device is not providing a “contact closure” it is providing a trickle current between the two contacts when water with some ionic content is present.
•	 The Leak sensor behaves as an open circuit when no water is present, and behaves as a (roughly) 1.4MΩ resistor when water is present. The resistance of it depends on your water.  
•	To confirm if the device is working, place the ohmmeter probes directly into water approximately 1.5” inches apart and take a reading. Then place the sensor in water and connect the ohmmeter to the red and white wires. The two readings should be similar. 
•	To get the best circuit design, put the sensor feet in water and measure the resistance with an ohmmeter.  Use this resistance in your circuit design.
•	In the unlikely event you have “non-conductive” water, it can be easily rectified by sprinkling some salt around the sensor location.  The water will absorb the salt, the salt will ionize the water, and allow it to conduct.
•	If you are using this sensor as an input to an Arduino or raspberry Pi, it is recommended to use either an Analog input, or a “PULL UP” input where the sensor is taking an input to ground.

### ⭐⭐⭐⭐⭐ Works well and seems solidly built
*by T***D on August 9, 2021*

I had previously asked a question through Amazon on how far I could extend the wires on this unit. The response I got was that it had only been tested up to 30 feet. I can confirm the product works fine at least up to the 50 feet of wire I used to extend it (I wasn't able to respond to my own question). I used typical CAT5e wire that I had around, bundling 4 of the 8 strands together to create 2 heavier gauge wires. Works just fine when paired with an Arduino using a digital PULL_UP pin and the onboard ground connection.
